My son loves Umizoomi. Unfortunately, the show was cancelled and all the toys are aftermarket which means they are crazy prices ($43 for a 4 inch $7 toy).
So I decided to make him a Bot backpack for his birthday. I had to wait three weeks to give it to him which was difficult especially since I wasn't sure he would still like the show by then!
I got a basic backpack pattern online then modified the front. It was a decent pattern but I would definitely make some changes next time. I also ran out of piping so the back isn't piped. That makes it more flimsy. But when I'm sewing at midnight over a coffee table, my attitude is get it done! Its good enough for a toddler!
He loved it. Had a huge smile on his face and wouldn't take it off. The only thing I couldn't find was a two inch disco ball for a zipper pull. That would have been the best final touch.
